Description
p53 is critically important in preventing oncogenesis but its role in non-cancer biology remains unclear. Macrophages exist as two subtypes (M1 and M2). Nutlin-3a (p53 activator) inhibits M2 gene expression and phenotype. p53 acts by suppressing transcription of c-Myc and thence regulates expression of a subset of M2 markers. This work has implications for our understanding of the mechanisms that regulate plasticity of macrophages in health and disease.

Description
Although various mechanisms have been inferred for combinatorial actions of multiple carcinogens, these mechanisms have not been well demonstrated in experimental carcinogenesis models. We evaluated mammary carcinogenesis initiated by combined exposure to various doses of radiation and chemical carcinogens. Female rats at 7 weeks of age were -irradiated (0.22 Gy) and/or exposed to 1-methyl-1-nitrosourea (20 or 40 mg/kg, single intraperitoneal injection) or 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (40 mg/kg/day by gavage for 10 days) and were observed until 50 weeks of age. The incidence of mammary carcinoma increased steadily as a function of radiation dose in the absence of chemicals; mathematical analysis supported an additive increase when radiation was combined with a chemical carcinogen, irrespective of the chemical species and its dose. Hras mutations were characteristic of carcinomas that developed after chemical carcinogen treatments and were overrepresented in carcinomas induced by the combination of radiation and MNU (but not PhIP), indicating an interaction of radiation and MNU at the level of initiation. The expression profiles of seven classifier genes, previously shown to distinguish two classes of rat mammary carcinomas, categorized almost all examined carcinomas that developed after individual or combined treatments with radiation (1 Gy) and chemicals as belonging to a single class; more comprehensive screening using microarrays and a separate test sample set failed to identify differences in gene expression profiles among these carcinomas. These results suggest that a complex, multilevel interaction underlies the combinatorial action of radiation and chemical carcinogens in the experimental model.

Description
The functional activity of TRPM7 is essential for cell viability and growth, and its expression is up-regulated in certain pathological conditions. In order to assess the effects of TRPM7 activity on cellular gene expression, inducible HEK293 cell-lines harboring the wild-type mouse TRPM7 and a mutant lacking the kinase domain were established.

Description
Promyelocytic Leukemia Protein (PML) was first identified as a fusion product with the retinoic acid receptor alpha in Acute Promyelocytic Leukemia (APL). Although PML has previously been studied in cancer progression and various physiological processes, little is known about its functions in Embryonic Stem Cells (ESC). Here, we report that PML contributes to the maintenance of the ESC self-renewal by controlling the cell-cycle and sustaining the expression levels of crucial pluripotency factors. Transcriptomic analysis showed that the ablation of PML renders ESC prone to exit from the nave and acquire a primed-like pluripotent cell state. During differentiation PML influences cell fate decision by regulation of Tbx3. PML loss compromises the reprogramming ability of embryonic fibroblasts to induced Pluripotent Stem Cells (iPSC) by inhibiting the TGF pathway at the very early stages. Collectively, these results designate PML as a member of the regulatory network for ESC pluripotency and somatic cell reprogramming.
